Last night, Treyarch debuted the first trailer for Call of Duty: Black Ops 2, and many fans were surprised by the premise of the new game. Rather than battle human soliders in past or present day settings, as has been the case in previous Call of Duty games, Black Ops 2 gamers will battle robots of the future - hijacked automated defense drones, to be exact.

Video gamers everywhere stormed entertainment stores this week, allowing Call of Duty: Black Ops to rake in $360 million in its first day on sale, a dramatic declaration that video game releases are on par with movie, music and book releases.

Activision Blizzard Inc. sold 5.6 million units the day the game was released, according to the company. The game’s predecessor, Call of Duty: Modern Warfare 2 sold 4.7 million copies in 24 hours, raking in $310 million on its first day. Within a week, that game made $550 million, so it will be interesting to see how this game pans in comparison.
